Not only that: It protects your data. The Unix security model is unfortunately stuck in the 1970s: It protects users from each other. That is a wonderful property, but in todays world you also need to protect the users from the applications they are running: Anything running as your user has access to all your data. And on most computer systems the interesting data is the one the users out there: Cryptogrqphic keys, login information, financial information, … . Typically users are much more upset to loose their data than about some virus infecting the OS files, those are trivial to fix.

Running anything as anlther user stops that application from having access to most of your data.

The same happens with any of the new immutable distributions. It’s just less effort as you do not need to do the nix configuration dance anymore.

Any of the many immutable distros (vanilla os, fedora silverblue, bluefin, aeon, endless os, pure os, …) will all obviously work.

Most of your customizations will live in your home directory anyway, so the details of the host OS do not matter too much. As long as it comes with the UI you like, you will be mostly fine. And yku said you like gnome, that installs many apps from flathub anyway and they work just fine from there.

For development work you just set up a distrobox/toolbox container and are ready to go with everything you need. I much prefer that over working on the “real system” as I can have different environments for different projects and do not have to polute my system with all kinds of dependencies that are useless to the functionality of my system.

NixOS is ofmcourse also an option and is quasi-immutable, but it is also much more complicated to manage.

Rustfmt is not very configurable. That is a wonderful thing: People don’t waste time on discussing different formatting options and every bit of rust code looks pretty identical.
